The quake was followed by eight aftershocks and the provincial civil affairs department was sending 4,500 tents, 3,000 quilts and other relief materials to Yao’an, Xinhua said.

Hundreds of police were dispatched to the disaster zone, it said.

Yunnan is a quake-prone, mountainous region that lies on China’s southern border with Thailand and Myanmar. It also borders Sichuan province, where a magnitude-7.9 quake last year left almost 90,000 people dead or missing.
